Enzymes affect a chemical reaction, making it easier to occur by reducing the activation energy; <u>option B</u>

<h3>What are enzymes?</h3>

Enzymes are biological molecules that alter the rate of chemical reactions occurring in the body.

Enzymes usually speed up the rate of reactions by making the reactions less energy-demanding, that is by lowering the activation energy of the biochemical reaction.

Enzymes are usually proteins, hence are affected by the conditions of temperature and pH.

Enzymes are also very specific in the substrate they act upon.

hich of the following describes the structure and function of the cell membrane? A. The hydrophilic head groups of the lipid mol
jeka57 [31]

The correct answer is: A. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell.

Plasma membrane of the cell is arranged in a bilayer of phospholipids. Phospholipids are amphipathic molecules which means that they have both hydrophilic and hydrophobic regions. The hydrophilic heads of phospholipids that are faced outward and hydrophobic layer located in the interior of the bilayer together make a good barrier between the interior and exterior of the cell, so the water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane.

How does a low protein intake affect homeostasis​
Thepotemich [5.8K]

Answer:

High dietary protein intakes are known to increase urinary calcium excretion and, if maintained, will result in sustained hypercalciuria. To date, the majority of calcium balance studies in humans have not detected an effect of dietary protein on intestinal calcium absorption or serum parathyroid hormone.

Which of the statements best describes the way you would engineer bacterial cells to produce a human protein?A. One restriction
erik [133]

Answer:

The correct answer is option D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA.

Explanation:

The way one could engineer bacterial cells to produce a human protein is by allowing bacteria to taking up the recombinant DNA. This recombinant DNA are inserted in the form of the vectors.

Recombinant DNA technology  or RDT allows individual fragments of DNA from any donor human genome to be inserted into vector DNA molecules with the help of the specific restriction enzyme for both vector DNA and donor DNA.

Thus, the correct answer is option D. The same restriction enzyme would be used to cut both the donor human DNA and the vector DNA.
